The court heard that following the discovery of Ms Wrightson’s body the investigation “led swiftly” to the arrest of the girls.

Ms Wrightson, who had been a well-known alcoholic in her community, was described as “small in stature and thin”.

The court was told that she was well liked, would give chocolates to young children and fed the local dogs.

But Ms Wrightson, who was known as “Alco Ange”, had got a reputation for going to the local shop to buy cigarettes and alcohol for children.

But as time went by, she came to complain about the “schoolies” and was described as “nervous” in the defendants’ presence.

The court was told that on the evening of December 8, at about 7.15pm, the girls let themselves in through Ms Wrightson’s unlocked door and remained inside for the next three-and-a-half hours, where they were to take a series of selfies.

Earlier in the day, the older girl’s mother was said to have “told her daughter to go and kill herself”.

Mr Campbell said that the last time Ms Wrightson had been seen alive was returning home from the local shop at 7.32pm.
